A vulnerability was found in Shlomi Fish Config-inifiles 2.70 and classified as problematic. This issue affects the function Config::IniFiles
of the file ini. The manipulation with an unknown input leads to a symlink vulnerability. Using CWE to declare the problem leads to CWE-61. The product, when opening a file or directory, does not sufficiently account for when the file is a symbolic link that resolves to a target outside of the intended control sphere. This could allow an attacker to cause the product to operate on unauthorized files. Impacted is integrity, and availability. The summary by CVE is:
The Config::IniFiles module before 2.71 for Perl creates temporary files with predictable names, which allows local users to overwrite arbitrary files via a symlink attack. NOTE: some of these details are obtained from third party information. NOTE: it has been reported that this might only be exploitable by writing in the same directory as the .ini file. If this is the case, then this issue might not cross privilege boundaries.
The weakness was presented 06/27/2012 (Website). The advisory is shared at bitbucket.org. The identification of this vulnerability is CVE-2012-2451 since 05/02/2012.
